Hello there.
I’m trying to balance an unbalanced monitor output which is 20ohms. The output trannies in question are the Lundahl 1539s which according the data sheet are best driven with a source impedance of negative 40ohms ( I didn’t know that’s a thing)
i wired them once as 1:2 and 1:1 with the latter giving me the best high frequencies response. The transformer sounds great and punchy however it totally kills any lower frequency and sounds like a low cut is applied.
Could this be because of the impedance mismatch? And if so: how would I go about lowering the source impedance of my monitor outs to -40 ohms without having to buy a new pair of transformers?
I’m a beginner so it might be that I mixed up some concepts of engineering just in case anyone reading this is confused.
thank you frens.
